Hey I'm new to this site and am not really sure if this is the place to post this but, all four of my antminer s3 units have stopped hashing.  I had my internet turned off and then I payed the bill the next day and now none of them work.  I have updated the IP address since that has changed and am still not getting any hashing.  I have checked all my network info many times and cannot find an error anywhere.  I even tried a factory reset on two of them and still nothing!!!!  Firmware rollbacks and even the latest firmware.  Nothing This is driving me mad here.  Any help would be much appreciated.  Please contact me if you can to help
